This invention relates to flashlights and more particularly to the assembly of the componentI parts thereof.

In somev flashlights 'the lamp socket supporting end lhas been positioned upon the end the lamp socket supporting end may be pery operations.

' realized, and in which:

structed as to retain the lamp socket supporting end permanently in operative position.

More particularly, in accordance with the invention, the lamp socket supporting end is means of a spacing member or insulating annulus of a shape substantially that ofv the flashlight casing, which spacin retained in place by an inturned ange formed In orderthat the invention may be clearly understood the same will now be described inf greater particularity in connection with the accompanying drawings illustrating one. modification by which the invention maybe 0 formed with passages therefor large enough Figure 1 is a longitudinal sectional view of the forward end of a flashlight showing the component parts in assembled relation.

JFigure 3 is an exploded view, in perspective, showing the component elements of the forward end of the flashlight in their order of assembly.

Iny the illustrated embodiment the Hashlight casingl or container for the batteries fibre'.

member is (not shown) is indicated at 10 and is prefn erably in thev'form of'a cylindrical tube and mayfbe of an insulatingmaterial, suchv as p Resting upon the :upper edge ofi-this -batterycasing 10 is a disc like end ,11,vsupporting the lamp socket 12' and of a diameter f substantially that of theoutside diameter of casing-10.A The .lamp socket-r12 passes through the centrally. disposed aperture 13 inthedise 1-1 and through the centrally disposed 'aperture in ajmetallic disc 14 withV which it4 makes electrical contact. The metallic disc 14 is connected to the end of a conductor 15, preferably in the form of a ribbon, leading to the switchy (not shown) on the battery container 10. rThe metallicdisc 14 is secured to the insulating discll conven- 4kiently by diametrically disposed eyelets 16y and one of these eyelets may also serve tosecure the conductor 15 in the electrical connectionV with the metallic disc 14. Insulated from'the metallic disc 14, say by a disc 17 of fibre or other insulatingmaterial, is the central` contact 18, which contact is adapted to makeelectrical connection with the positive pole of the flashlight battery and is exposed for connection with the terminal of the lamp not shown through the apertures in the insulating.' end disc 11 and metallic discl 14. The contact 18 is conveniently secured to the end disc ,11 by the eyelets 19 which may for the sake offconvenience in manufacture and to strengthen thel` disc assembly, pass Vthrough all of the parts, to wit, end disc 11l and fibre disc 17, the metallic discv14 being.V

so thatfno electrical. contact is made .there- 4with.

To properly ,position the lens reflector withrespect to the flashlight lamp carried by theendll, the hood collar 2O extends a material distance above the end 11 in order that ico ing member 22 of cylindrical form and of interior and exterior diameters substantially the same as the battery casing 10 is adapted to be positioned upon the end disc 11 and retained thereagainst by an inwardly directed flange 23 formed on the hood collar 20.

To assemble the forward end elements of the flashlight, therefore, it is merely neces-` sary to set the end disc 11, carrying the contacts and lamp sockets, upon the end of the flashlight casing 10; place the cylindrical spacing member 22 thereupon and telescope the hood collar 20 over the assembled'parts 10, 11 and 22 until the flange 23 rests upon the outer end of the spacing member 22. To

secure the parts together thereafter it is only necessary to secure the hood collar to the battery casing 10 which may be accomplished by means, say, of one or more eyelets 24 or by staking the hood collar to the casing 10,

It will thus be seen that the flashlight end ispermanently and securely mounted upon the end of the battery container so that the hood and its associated parts are carried at the proper position with respect to the lamp by operations of assembly of eXtreme simplicity requiring only fastening operations of a simple nature.

Various modilications will occur to those skilled in the art in the configuration and l composition of the component elementsgoing to make up the flashlight end structure as well as in the devices used to secure the hood collar to the battery casing without departing from the spirit and scope of the invention as set forth in the appended Claim. What I claim is v In a flashlight, in combination, a cylindrii cal battery containing a casing of non-conductive material, a lamp socket support comprising a disc of non-conductive material seated upon the end of the casing and of a diameter substantially that of the casing, a cylindrical member of non-conductive material of substantially the same outside diameter as the outside diameter of the casing and seated upon said lamp socket support disc, a hood collar telescoped over said end of the casing and formed with an inwardly extending flange at its outer end to engage the end of the cylindrical member remote from the lamp socket support disc, and means to permanently secure the hood collar to the casing to retain the vparts rigidly together.

In testimony whereof I aliix my signature. JAMES T. BROWN.
